No DTS playback, not capable of lower and higher frequencies, control's screen looks very alphanumeric (old style) does not have special settings (like hall, stadium etc.), no control over use of speakers for aux. audio or radio. setting up radio presets is confising, the remote control has most control buttons togehter and are the same size (all squares) makes it easy to press the wrong button... Excellent price for a poor guy like me though!!! Got it at best buy for 185.00 U.S. Dlls.
